Abstract: front page image
(EN)Disclosed is an asynchronous multiple access method and device for a low latency service. The asynchronous multiple access method for low latency service may include the steps of: grouping, by an eNB, each of a plurality of UEs into one UE group among a plurality of UE groups in consideration of each of a plurality of propagation delays of each of the plurality of UEs; receiving, by the eNB, each of a plurality of pieces of uplink data transmitted by each of the plurality of UE groups on each of a plurality of wireless resources allocated for each of the plurality of UE groups at an internal access timing; and transmitting, by the eNB to each of the plurality of UE groups, each of a plurality of ACKs/NACKs signals in response to each of a plurality of uplink frames, wherein the internal access timing can be periodically defined in a symbol unit for the synchronization of transmitting times of the plurality of pieces of uplink data.
(FR)L’invention concerne un procédé et un dispositif d’accès multiple asynchrone pour un service à faible latence. Le procédé d’accès multiple asynchrone pour un service à faible latence peut comprendre les étapes consistant à : grouper, par un nœud B évolué (eNB), chacun d’une pluralité d’équipements utilisateurs (UE) en un groupe d’UE parmi une pluralité de groupes d’UE en prenant en considération chacun d’une pluralité de retards de propagation de chacun de la pluralité d’UE ; recevoir, par l’eNB, chacun d’une pluralité d’éléments de données de liaison montante transmis par chacun de la pluralité de groupes d’UE sur chacune d’une pluralité de ressources sans fil attribuées pour chacun de la pluralité de groupes d’UE à une temporisation d’accès interne ; et émettre, par l’eNB à destination de chacun de la pluralité de groupes d’UE, chacun d’une pluralité de signaux d’accusé de réception (ACK)/accusé de réception négatif (NACK) en réponse à chacune d’une pluralité de trames de liaison montante, la temporisation d’accès interne pouvant être définie périodiquement dans une unité de symbole pour la synchronisation de temps de transmission de la pluralité d’éléments de données de liaison montante.
(KO)저지연 서비스를 위한 비동기 기반 다중 접속 방법 및 장치가 개시된다. 저지연 서비스를 위한 비동기 기반 다중 접속 방법은 eNB가 복수의 UE 각각의 복수의 전파 지연 각각을 고려하여 복수의 UE 각각을 복수의 UE 그룹 중 하나의 UE 그룹으로 그룹핑하는 단계, eNB가 내재적 액세스 타이밍에 복수의 UE 그룹 각각을 위해 할당된 복수의 무선 자원 각각 상에서 복수의 UE 그룹 각각에 의해 전송된 복수의 상향링크 데이터 각각을 수신하는 단계와 eNB가 복수의 UE 그룹 각각으로 복수의 상향링크 프레임 각각에 대한 응답으로 복수의 ACK/NACK 신호 각각을 전송하는 단계를 포함할 수 있되, 내재적 액세스 타이밍은 복수의 상향링크 데이터의 전송 시점의 동기화를 위해 심볼의 단위로 주기적으로 정의될 수 있다.
